Identifying And Fixing Problems With Camellias
The following are some common problems with camellias:
1) Yellow Leaves – This problem occurs mainly in old, diseased or damaged plants.
You will see that the leaves turn yellow from time to time. Sometimes they fall off completely and die.
Other times they remain green but become limp and wilt under your feet. They may even dry up entirely, leaving them looking like dead wood!
2) Leaf Drop – This problem occurs when the plant’s water supply dries up and it cannot get enough moisture from its roots to keep growing.
Usually, this happens during drought conditions. When this happens, the stem and leaves begin to droop down until they eventually fall off completely.
If left alone, the plant will recover itself after a few days of rest. However, if the plant does not have enough water to survive, then it will die.
3) Fungus Damage – This problem occurs when certain types of fungi attack the stems and leaves of the plant.
These types include whitefly, powdery mildew and rust fungus. All these kinds of fungi cause damage to the stems and leaves causing them to rot away.
Some types can kill a tree within a year if allowed to grow unchecked!
4) Sunburn – This problem occurs when the leaves and stems do not have enough protection from the sun.
Even though camellias naturally grow in the shade, it does not mean that they cannot get sunburnt! If the leaves do not have enough protection or if the plant is young and still growing, it can get sunburnt.
When this happens, you will see brown patches on some of the leaves which will eventually turn yellow and fall off. You can protect your plants by using a shade cloth.
5) Salt Burn – This problem occurs when the plant is placed next to a road that is frequently used.
Salt and other chemicals from the road can burn the leaves of the plant if they are not protected. If this is the cause of the damage, then it may be too late to save the camellia, although you can try using a thick layer of mulch around the base to act as a buffer against the salt.
6) Mice – This problem occurs when rodents such as mice or rabbits decide to eat your plants!
Although they eat the leaves, stems and even the roots of your camellia, it is rare for them to kill it completely. The only solution to this problem is to get some traps and place them around the plant.
Make sure you get the right type of trap, as some are better than others at catching certain types of rodents.
7) Grubs – This problem occurs when beetle grubs burrow into the roots of your plant.
These grubs eat away at the roots of your camellia and eventually kill it if left untreated. You can treat this problem by using specialised root killers along the base of the plant.
Make sure you follow the included instructions carefully and that the product is safe to use on camellias.
